Adventure Time: Side Quests is the reboot the franchise desperately needs

A lot happened in the 278 episodes in between as Adventure Time evolved from a whimsical kids’ show about a boy and his magic dog into… something else. Over 10 seasons, the fantastical land of Ooo was revealed to be the post-apocalyptic husk of Earth in the distant aftermath of nuclear war, while various, once-cartoonish characters received complex, tragic backstories.
